The Pikachu, which is a New 3DS Pokemon 20th Anniversary edition with aftermarket plates (dual IPS) I use almost exclusively for Pokémon games (though I do have the stock Blastoise plates). I still play a lot of Gen 4/5 and Mystery Dungeon, so it looks better than on the XL.
The SNES New 3DS XL I use for most of my other physical Nintendo games (LoZ, Smash, etc).
And the blue OG 3DS XL is modded and I use for playing GBA and modded games.
Fortunately I'm no longer feeling the urge to purchase new consoles, I think this is the collection I'll stick with. But I'm very happy with it.
